guidelines that limit Radio Frequency (RF) energy
exposures. The FCC established these guidelines
in consultation with the FDA and the other federal
health and safety agencies. The FCC limit for RF
exposure from wireless phones is set at a Specific
Absorption Rate (SAR) of 1.6 watts per kilogram (1.6
W/kg). The FCC limit is consistent with the safety
standards developed by the Institute of Electrical
and Electronic Engineering (IEEE) and the National
Council on Radiation Protection and Measurement.
The exposure limit takes into consideration the
body’s ability to remove heat from the tissues
that absorb energy from the wireless phone and
is set well below levels known to have effects.
Manufacturers of wireless phones must report
the RF exposure level for each model of phone to
the FCC. The FCC website (http://www.fcc.gov/
oet/rfsafety) gives directions for locating the FCC
identification number on your phone so you can find
your phone’s RF exposure level in the online listing.
8. What has the FDA done to measure the Radio
Frequency energy coming from wireless
phones?
The Institute of Electrical and Electronic Engineers
(IEEE) is developing a technical standard for
measuring the Radio Frequency (RF) energy
exposure from wireless phones and other wireless
handsets with the participation and leadership
of FDA scientists and engineers. The standard,
“Recommended Practice for Determining the
Spatial-Peak Specific Absorption Rate (SAR) in the
Human Body Due to Wireless Communications
Devices: Experimental Techniques”, sets forth the
